I don't know quite what I expected from PhD-land. I knew I had a lot to learn. I was very scared about this. I knew that there were going to be a lot of people who knew a lot more that me. I was very scared of this. I knew I was going to be a lot older than most of the other post graduate researchers, and even some of the post docs. I was very scared of this. And I knew I was going back into full time education, somewhere I had escaped from 5 years before. I was very scared.
However, I knew I was going to be doing some work that could have a real impact, and this was the thing that excited me the most.
On the first day, I had my bag all packed with the text books, note books, pens, pencils and everything one would need for the first day of school.
Things for the first day
The first month or so was getting used to everything. I spent time researching different turbine types, looking at their performance characteristics and where they are used. I learnt a lot about power electronics, the basics on how they work, what they do and so on, and build a switch-mode power supply (SMPS). This can take any voltage level input and give a constant voltage output, and is the backbone of many modern power supplies.
The switch-mode power supply
It was fun building the SMPS, I hadn't really build many electronic circuits before, so the method and testing of it was quite new to me. However, after a quite a few burnt fingers, a little bit of swearing, and putting things around the right way, I eventually got it to work.
I then started to look at the research in the field of pico hydropower. There is surprisingly large amount out there, different people experimenting with new turbine concepts, controllers, generators and loads. The whole spectrum. I realised that although I was going to become an expert in this, it would be just a small area. I would though need a good understanding of all the issues surrounding them as well.
In November, I took a few days off to see a friend in Cockermouth, up in the Lake District. The weekend I planned was one week after the terrible floods up there, the devastation was incredible. The high street was free from water again, but all the shops and houses along there were ruined. We went to nearby Keswick, which didn't get any flooding. It's amazing how localised things like that can be.

At the beginning of December all the press were focussed on Copenhagen. All the world hoped that an agreement could be made to help stop the climate change calamitous spiral we have set ourselves on. Although everyone is responsible, we do look to our governments for leadership as well. As a part of this, I joined a march in the centre of London called the Wave. Groups from all across the UK, religious, environmental activists, aid organisations, and ordinary people turned up to show how important getting an agreement was. At 3pm on a rainy afternoon, we all waved at the Houses of Parliament to show that we cared and wanted them to represent us with action. However, as we all know, they all left Copenhagen with nothing. Another seemingly impotent gathering of world leaders who can only talk and not actually do anything.

And then it was Christmas. I wasn't quite sure where the time had gone. I had achieved some things, a plan of what I wanted to do for the next few months, I'd found a number of useful papers and was slowly understanding where the level of technology was that I wanted to use. I also was learning about practical electrics, and so decided to light up the lab a little.

As Christmas party season approached, I was looking forward to seeing my old office friends, and going home. I had only really had a couple of weeks at home since returning from Nepal in April, what with work, university and other things.
And so here I am. So, Happy Christmas, and here's looking forward to a great 2010!
